Ejecting is very risky for the pilot. Many pilots are seriously injured in the process (1 in 3 chance of spinal injury https://www.smh.com.au/education/how-dangerous-is-it-to-ejec...). Ejection is the option of last resort; I'm guessing the pilot felt that he wasn't quite that desperate yet.

_jack_coxon Freevolt can power a low-energy device forever, and for free

There is PDF buried in the developers section that says that they can get 100µW with a single antenna and multiple antennas can be combined to increase the power. I think a continuously powered device would not be a good application. Instead a device that powers on occasionally where the FreeVolt is trickle charging a battery would be a better application.
